A self-guided detective murder mystery through Hellevoetsluis, from Fort Haerlem to the lighthouse.
A murder in Hellevoetsluis, one victim called Balthasar, and a suspect list that only gets shorter if you go and look.
It is a murder mystery game in outdoor form. You walk Hellevoetsluis, the story comes to meet you, and every location holds a puzzle, a code or a photo task that crosses another name off the suspect list. Self-guided from the first step: you pick the day, you pick the hour, you set the pace.
Names that turn up in the case notes: Molen De Hoop, Nationaal Brandweermuseum and Ramtorenschip Buffel.
The Walk Through Hellevoetsluis
Jan Blanken Droogdok and Kustbatterij Hellevoetsluis belong to the same case. You cover 3 to 4 km in all, and there is nothing stopping you sitting down halfway.
Playing the Detective Game in Hellevoetsluis
You move, the case moves. Each stop has something to solve and each digital character has something to say once you have solved it, and the suspect list shortens accordingly. Figure on 1.5 to 2 hours across 3 to 4 km, with as many breaks as you feel like taking. The habit is the one the Sherlock Holmes stories are built on: notice the thing nobody else bothered to look at, then say out loud what it means.
Friends, Families and Colleagues in Hellevoetsluis
With friends. A better answer to "what shall we do today" than another cafe. It works as a pair and it works as a four, and it gives you something to disagree about over dinner.
With your team. Buy a ticket per four, put every team on the same murder, compare the answers over lunch. Nothing to hire and nobody to brief, so a company outing in Hellevoetsluis survives people turning up late.
With kids. The puzzles work from about eight years old. Younger ones walk along and help, older ones take over the phone, and the whole thing survives being interrupted by ice cream.
Frequently Asked Questions
How does the murder mystery game work?
Everything sits in the Loquiz app. Start it wherever you like in Hellevoetsluis, follow what the case tells you, solve what each location puts in front of you, and hand in a name when you are sure.
How long does it take?
Set aside an afternoon. The case itself takes 1.5 to 2 hours across 3 to 4 km, but nothing counts down and nothing shuts, so the breaks are free.
How many people can play on one ticket?
One ticket covers one to four players on a single device, €19.95 in total. Bigger groups buy one ticket per four and race each other through the same murder.
Do we need to book a date?
Yes, a date. The hour is yours to choose, because nobody is standing anywhere in Hellevoetsluis expecting you - no meeting point, no guide, no group.
Is it suitable for children?
Yes, from about eight. The difficulty is easy, the walking is gentle, and children tend to be the fastest in the group at the photo tasks.
What happens if it rains?
You decide when to play and you can pause whenever you want. Step inside, wait the shower out and pick the case up again - no clock is running and nothing closes.
Is this a detective game or a walking tour of Hellevoetsluis?
It is a detective game first. But you see Hellevoetsluis properly while you play it, and people tend to remember a street they searched better than one they were shown.
What else is there to do in Hellevoetsluis?
The same streets carry other city games in Hellevoetsluis, each with its own story, and anyone travelling on will find the next stop under the Netherlands.

I had a fantastic experience with CityGame! The concept is creative, engaging, and a great way to explore a city in a completely new way. The games are well-designed, combining puzzles, storytelling, and adventure so you’re constantly discovering something interesting around every corner. What I especially love is how CityGame turns a normal walk through the city into an interactive experience. It’s perfect for friends, families, or team outings, and it makes sightseeing much more exciting than the usual tours. Everything was easy to use, the challenges were fun and clever, and it really encouraged us to look closer at the city and its hidden details. Highly recommended if you’re looking for a unique and memorable way to explore!

This is an interesting way to conduct a self-guided Amsterdam city tour. It used the GPS on your phone to guide you to stops on a route. There are mini quizzes once you arrive at the stops on the path. The quizzes draw your attention to features in front of you or to a brief history of the place. In many cases, we visited a spot that would not have been obvious as a regular passer by. The tour as a whole was interesting to us as newcomers, but I would have liked more information on many locations we visited - a few links outside of the app for each place would have been helpful. Beyond that, the interface was a bit clunky and sometimes awkward to navigate. We definitely don't regret trying this out and feel like we got our money's worth on the experience.

This was a fun game! It had a few challenges which was good and surprises. It got me to go around and explore Queenstown, New Zealand. I got to places in Queenstown, New Zealand I hadn’t been to before while on holiday here. Thank you for that and it gave a feel what it would be like to be the actual Sherlock Holmes!
